NTSB narrative
The pilot reported that while flying near the top of a canyon in cruise flight, the climb performance of the airplane began to decay, and it became difficult to maintain altitude. The pilot elected to continue the flight through the canyon, and as the performance further decayed, the airplane descended below the canyon rim. The pilot stated that he made "fairly steep turn" around the corners, losing altitude each time. At an altitude of approximately 200 feet above ground level, he decided to initiate a precautionary landing in an open area near the Green River. During the landing sequence, the airplane impacted several large rocks before it came to rest upright near the river where a post crash fire ensued, consuming the airplane. The pilot reported that at the time of the accident, there were no mechanical anomalies with the airplane or engine. Using the recovered weather observations from a weather recording station located about 41 miles east of the accident site and the accident site elevation; the NTSB investigator-in-charge calculated the density altitude to be 6,708 feet msl. The pilot reported that at the time of the accident, he estimated the weight of the airplane to be 2,040 pounds. The certified maximum gross weight of the airplane is 2,150 pounds.
Probable cause
The pilot's inadequate in-flight planning and decision to continue flight into a canyon area with questionable aircraft performance. Contributing to the accident was the lack of suitable terrain for the precautionary landing and a high density altitude condition.

Source notes (5)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
- API snapshot SHA-256: e0fdee8fe71f51aee2b1263ba2bc057b80034a61ab59b1bdea785a1a25041ab2; retrieved 2026-09-15T09:53:00.417Z.
- Corrected after a review of the NTSB narrative, which states these values explicitly: damage. The narrative states a post crash fire ensued, "consuming the airplane".
